Abstract

The formation of micelles in a solvent that is selective for one of the blocks is one of the most important and useful properties of block copolymers. Recently, we have synthesized copolymers of polyethylene glycol and various dimethyl esters, which self‐assemble into nano micellar aggregates in aqueous media. These nano micelles are very effective in solubilizing otherwise insoluble drugs. The structure, interaction and size of these nano micelles are very important and critical to design an efficient drug delivery system. In the present work, we have studied the effect of hydrophilic block, PEG length, linker, concentration and temperature on these nano micellar structures and interactions by static light scattering techniques.
